To all iii/"10m it only concern;

Be it known that i. Cnilnmin D. llm'rott. J11, a citizen of the UnitedStairs. l'tzh ldlllg at Providence, in the eonntv ot lrovidenre andState oi Rhode island, have invented a new and useful,illll'ilOi'ClDtllt in l lxploeivewhieh the following in aspot-itication.

This inn-ration relates to certain nevi" and useful inzpmveniente inexplosive engines.

The invention partieularlr relates to and resides in the rotary valvvvhi h ('mixh t'sf of a solid rod or Shaft having rut-away por-. tionsfor the pnriose out rontrolhng' or gov erning the intake and theexhaust.

The ohjeet of the. invention is to produce a alve of this eharaeter\vhieh will he ellirient in eperatioi'i and which will he possessed ofgreat strength and longevity.

In the drawingg e' Figure l is a. eentral vertical v eetional view of afour-cylinder engine. Fig. section of one of the eylindem and itspiston. Fig. 3 is a fragmentary end elevati t n and Fig. 4 a detailperspective. view of the rotary valve.

In the drawings, the engine easing is des ignated l and. is formed withfour cylinders 2 in which reei 'nfo wate the pistons 3. the lat- I terbeing ronneeted to the eranlt nieehanisn'l 4- by means of the pistonrode a. The upper ends of the evliudei are formed with a, *alve seat 6n'hieh extends from end to end of the easing; 1 and through all of theeylinders A valve 7 "vvhieh is eonipoeed of an elongated solid red orsha'lt is mounted in the valreseat so as to rotate therein, and isformed with eigl'it ports each port l'ieing of quadrant town in ereseetion, the ports designated 8 in the drawii'igs are inletports and theremaining l' ll1' 'pt)li de ig'iiated 9 are the oiitlet. or exhaust;ports. It will he eeen by reference to the drawings that there in anexhaust port and an inlet port for each cylinder, said ports being die--}'Josed atright :iirglim to each other. Eve shown in Fig. 2 ol' thedrawings, the ports; are termed hy out-away pmtitnlf; \vhieh aresnliistantiallv semi-eireular in cross 56(l'io1l and which, havelJOtllmls whieh extend in a 'ejht tmnsverse of the length of the valvein order that, when the valve is in 2 is a 'tragu'ientary transverseFour of DDE ISLAND.

the position shown in l ig it will he closed and when turned at rightangles to the poeition shown in l ig. r2. eoinnniniealion will. heestahlished between the interior of the evlinder and the exhauet orinlet pipes. As shown in the drawings, the top of the easinn 1 is formedwith integral. hooddike extensions l0 \vhieh regi ter with openings l1Wlli(l1 are rut through the, top of the easing and are adapted toregister with the valve openings 9. and! respertivelv of the, valve.

As shown in Fig". the valve seats 6 are formed in the top oronter endwalls of the evlindere n'herehv the valve rod projects on o 'ipositeaides o1" eaid walls. the mouths of the ports and 5) being ofsutlieient; length so as to have their ends extend beyond said oppositesides of the cylinder end Walls to therel'rv permit eonnnunieationbetween the hood interiors and that of the cylinders. The inner ends ofthe hoods l0 terminate at the inner alLlU of the valve seat 6, the topsof the hoods extemiling' over the tops ofthe eyliuders and the oppmiteends thereof be inn direeted dgnvmvardly.

The rotary valve driven from the crank shaft; 4 by means of any suitabletype of gearing such it r i'ostanee an that'depieted in the drawing Therelative speed of the crank Shaft and valve is 2 to 1, so that the valvewill he ro tated ;-=o us to alternately bring" the exhaust and inletports For eaeh ovlinder into register with the respective exhaust andinlet pipes 1i? \v hieh are eenneeied to the hoods 10.

it will he seen that v\iuee toe valre shaft or rod in of solid (roseeeetion, it is pens qHed of egreat str ngth and increased longevity a8eonipared with a hollow rotarjv valve.
